Tried to switch rolls of laminate on our new Excelam Q1400 cold laminator, short story not successful, so put the old roll back on and then the trouble started. The paper take up roll that feeds under the prints and protects the rollers from the laminate adhesive, starts to crease badly. Doesn't seem to want to work itself out and affects the quality of the laminate on the prints. I think its a tension issue, but can't seem to work it out. Can't laminate till its resolved. Any ideas or tips would be appreciated.

did you change anything else? Were the 2 lam widths the same? if not, did you adjust the location of the roll across the width of the roller?
I have a 62" GBC laminator, and my left fitting is set so that it remains in the same location for the 2 sizes of lam that I use, 38" and 52"
When I use 52", it is set to the exact center, as I was taught it should be, because the rollers are designed to "crown" ever so slightly. I've had problems with my kraft paper crinkling & asked a lot of questions about it too. On my 38" material, I'm set far enough off to one side, that not being centered hasn't been a problem for me.
Another thing to check, is that some laminators have independent adjustments for the thickness of the space between the 2 rollers. If you set them as close as you can without touching, you can "measure" that space using a small stack of typing paper. On mine, I can fit 9 sheets in one side before it just starts to roll the roller, but the other side fit 14 sheets. I haven't found how to adjust this, but I can see how it would contribute to the problem. It has been working out, so I've left it like that, but you might want to check that yous is not further out of whack.

I've really grown to hate my laminator. I had an employee suggest having the soft silicone rubber sleeve bottom roller covered with permanent rubber. I assumed they would apply a very similar rubber but nooooooooo, they used a very hard rubber. Now I can't even use it to mount prints or lam. Doug, I saw your testimonial on the Big Squeegie so I ordered a couple of them last week. They came in Thursday and I was out of town Friday so I haven't had a chance to use them yet. I'm looking forward to it though.

try running some scrap at almost no tension, then build the tension up from there, too much tension is usually the problem. I'm not familiar with that machine but the principles are the same, does it have settings or is it more by feel? if all else fails call the supplier of the machine and the films, they should be able to help. Also try a long run of just paper, if it tracks straight then you have even tension side to side and watch for nicks in or adhesive on both rollers
